r when releasing the ship from its mooring, such operation requiring menon the wharf or pier to unloosen the hawser connection, or men from theship to perform this function and thereafter board the ship. Manyattempts have been made to overcome such disadvantages, but with scant fsuccess, and, therefore, the principal object of this invention is toovercome such disadvantages, including a saving in labor, and eliminatewear and tear of the hawser line by virtue of its connection with theanchor medium, by providing a releasable ships hook or anchor mooringdevice adapted to be readily connected with an anchor mooring ringconnected to an anchorage medium adapted to assure at all times, despitethe automatic release feature, a dependableanchorage, incapable ofaccidentally becoming disengaged and whereby disconnection of themooring device and anchor ring may be effected from the ship as desired,and Without the aid of manual operation from a pier or like anchorage.

One of the principal objects of this invention is the provision of aships hook engageable with an anchor ring or other medium and includingmeans for releasing said hook therefrom irrespective of whether the loadconnection with the hook and ring is slackened or not.

Another important object of this invention is the provision of a shipshook attached to one end of the mooring cable or hawser and releasablemeans associated with the hook, whereby when force is applied thereto atwisting or rotary movement is imparted to the hook to effect itsdisengagement from its anchor mooring means with out necessitatingslackening of the hawser, and without regard to load conditions.

Another important object of this invention is the provision of a shipshook of this character of a predetermined configuration wherebyaccidental disengagement of the hook is precluded,

so designed as to withstand heavy load stresses and adapted to bedisengaged from its anchoring ring or other medium without materiallyshifting the attached pivotal end of the hook with respect to said ringand without necessitating slackening of the connecting cable, by virtueof the rotary movement imparted to the book by the fulcrum constructionof the releasable member pivotally carried by the hook, when force isapplied through the release cord connection to said fulcrum member.

A further object of this invention is the provision of a mooring hook asabove described including a tangentially extending lug pivotallysupporting a fulcrum member to which is attached a release cord, andincluding an auxiliary anchor rope element having one end attached tosaid lug and having a ring spaced from said attached end and a ringsecured to its free end, said hook adapted to engage said rings whensaid rope is passed around or through a stationary anchor means, wherebywhen the hook is released from said rings, said rope is released fromits anchor means and adapted to be drawn with said hook back to theship.

With theseand other objects in view, which will become apparent as thedescription proceeds, the invention resides in the construction,combination and arrangement of parts, hereinafter more fully describedand claimed, and illustrated in the accompanying drawing, in which likecharacters of reference indicate like parts throughout the severalfigures, of which:

Fig. l is a fragmentary side elevation of a vessel moored to a pier bymeans of my improved releasable mooring hook device.

Fig. 2 is a side elevation of my improved ships hook operativelyconnected with its anchoring other means of effecting a mooringconnection to a dockpost or the like.

There have been various attempts to effect detachable anchor hooksemploying trigger and latch mechanisms but such structures have provenunsatisfactory and deficient in many respects, such as employing amultiplicity of parts, requiring expensive construction, and inconnection with heavy load stresses the movable parts becoming fixed andfailing to properly function, and it was to overcome such deficienciesand to provide an anchor hook device so shaped as to preclude itsaccidental disengagement, comprising no trigger or movable parts adaptedto become out of order and tending to prevent ready attachment of thehook to a mooring ring structure, said hook having mounted thereon afulcrum element attachable to a release cord so that movement of thecord in releasing direction transmits force through said fulcrum elementto the hook substantially at right angles to the load or connectingcable at its point of connection, and owing to the predetermined angularshape of the hook effecting its rotary movement at said point ofconnection without, to any great extent, shifting its pivotal point, atthe same time effecting disconnection of the hook and its anchor withoutnecessitating, slackening of the load line, that I designed the deviceforming the subject matter of this invention.

In the illustrated embodiment characterizing this invention there isshown a ship A, dock or pier-post B and ships hook or anchor device C.The ship or vessel A has a hawser or mooring line 5 adapted to besuitably connected to an anchor mechanism or mounted on any suitablewinding mechanism, not shown, and in the present instance, projectingthrough a porthole 6 with its ince end extending through link or ring Iand secured therein as at 8 or in any suitable manner, said link beingsuitably mounted in opening 9 formed in one end of the anchor or mooringhook I ll.

curved bill-like formation H tapering from a point opposite opening 9 asat it to its free end 53 which extends by and beyond its load connectingend M as will be apparent.

The arc of said bill-like portion from point l2 approximately to itsfree end is substantially its opposite end as at It to receive one endof a release cord or cable secured therein as at 2 I, similar to hawser5 as at 8, and projecting downwardly from the under surface of saidmember 16 is a triangular portion 22 adapted, when pulling force isapplied to cord 28, to engage hook NJ as at 23 and impart thereto atwisting or rotary movement of said hook about its pivotal .axis as at9, as and for a purpose hereinafter more fully appearing.

Suitably connected to the anchor or pier-post B or other suitableanchoring element, which may be a buoy or other anchor means, is an eyemember 24 rigidly secured to the post in any suitable manner and havingmounted therein an anchor ring 25 adapted to receive hook ill firmlymooring ship A as will be well understood.

While I have described the device C as effecting a mooring connection byengaging the hook it] in anchor 1ink25 secured to anchor post B it maybe desired to anchor directly to apost B not equipped with ring 25, andin Fig. 4 I have illustrated the manner in which this'may be easilyaccomplished. rope 26 may be employed having its free end suitablyconnected to lug l5 as at 21 and spaced therefrom secured as at 28 isaring 29, and suitably secured to the free end of said rope 25 is asimilar ring 39, so that when rope 29 is passed around anchor post B andhook H! inserted in rings 29 and 30. the mooring operation is completedas in the first instance. It is further noted that the rope 26intermediate ring 29 and point of connection 27 presents a loose loopwhen the hook is in operable position, and to Hook ill terminates in aAn auxiliary hawser or' disengage the mooring connection it is onlynecessary to exert a pulling force on the release cable 20 therebyeffecting disengagement of hook Hlfrom rings 29 and 30, similar to theoperation described in connection with ring 25, and rope 26 will becarried back to the ship along with hook C as will be apparent.

It will be noted that the mass of the hook is such that when the pullupon the pivotal point is released, as for instance, the movement of theship toward the dock, the action of gravity will force said hook to movein a direction which will further its engagement with the ring, andthereby preclude its accidental displacement.

While the operation of the device would seem to be clear from the abovedescription it might formly curved throughout a substantial portion.

of its length, so that the arc of the bill is such that the center ofits radii is located at the pivotal point and for the further reasonthat the config uration of said hook tends to aid in effectingdisconnection of the hook from mooring ring 25 without regard to loadconditions, the load itself tending to complete the disconnection as themooring ring approaches the free end of the hook.

From the above it is apparent that I have designed a releasable mooringdevice, adapted to save time in anchoring a vessel, eliminating wear andtear of the hawserat its point of connection, while adapted to eliminatetrigger and movable latch connections, so designed as to preventaccidental disengagement by reason of movement of the ship with thetides, adapted to be remotely controlled from the vessel, yet one simplein construction, comprising few parts,

manufacturable at a reasonable cost and efiicient for the purposesintended.

Although in practice I have found that the rificing any of theprinciples of this invention.

Having thus described my invention, what I desire protected by LettersPatent is as set forth in the following claims;
